Revitalization of rotational biological contactors

Abstract

Treatment of waste water in rotating biological contactors (RBC) requires knowing technical and technological conditions and understanding of microbiological processes. Deficient knowledge of these processes and operating problems has led to decrease efficiency of RBC or even its dysfunction. This paper analyzes improvement of efficiency of waste water treatment in RBC with microbiological product adding. Revitalization of RBC was conducted also. Effect of treatment was followed through concentration of analyzed components while through their removal percentage achieved efficiency was analyzed. .

Procesi prečišćavanja otpadnih voda u rotirajućim biološkim reaktorima ('Bio-disk' uređajima) pored poznavanja tehničkih i tehnoloških uslova zahtevaju i dovoljno poznavanje mikrobioloških procesa. Nedovoljno poznavanje ovih procesa ili operativni problemi u toku rada doveli su u velikom broju slučajeva do smanjenja efikasnosti rada ovih uređaja ili do njihovog zastoja u radu. U ovom radu je analizirano podizanje efekta prečišćavanja u rotirajućim biološkim reaktorima uz doziranje mikrobiološkog preparata, a ujedno vršena i revitalizacija rada 'Bio-disk' uređaja. Efekat prečišćavanja je praćen preko vrednosti koncentracije analiziranih komponenti, a postignuta efikasnost analizirana preko procenata uklanjanja istih. .
